Quran 7:18 — The Purgatory (Al-A'araf)

He said, "Get out therefrom, despised and defeated. Those among them who follow you, I will fill Hell with you all.

[7:17] "I will come to them from before them, and from behind them, and from their right, and from their left, and You will find that most of them are unappreciative."

[7:19] "As for you, Adam, dwell with your wife in Paradise, and eat therefrom as you please, but do not approach this one tree, lest you fall in sin."
